Call it a shock discovery: DNA research has revealed two entirely new species of electric eel in the Amazon basin, including one capable of delivering a record-breaking jolt.The findings are evidence, researchers say, of the incredible diversity in the Amazon rainforest -- much of it still unknown to science -- and illustrate why it is so important to protect a habitat at risk from deforestation, logging and fires.In pic: This undated photo provided by researchers in September 2019 shows an Electrophorus voltai, one of the two newly discovered electric eel species, in Brazil's Xingu River.
